Route Switched Path (RSP) Scheme Each egress RSP node is assigned an IP TE prefix, which should be non-globally routable Ingress RSP node decides the path to egress based on traffic engineering requirement just as in MPLS TE Instead of use Label Request Object in Path message, it uses IP Route Request Object Instead of use Label Object in Resv message, it uses IP Route Object. The IP Route Object contains the IP host route allocated by the egress for this RSP Each RSP node along the path installs the IP host route in RIB/FIB towards the path nexthop |
